Hello:
It was working before, but now ubuntu 10.10 doesn't allow my windows xp computer to connect to //home/my name/public folders. I really didn't change anything.

The permissions are set correctly to create and delete files in Owner, group and others headings in permissions

Tried to share the public folder but got the following error:
'net usershare' returned error 255: net usershare add: cannot convert name "Everyone" to a SID. Memory allocation error.

I have no idea whats going on, please help?


Here is my samba file

#
# Sample configuration file for the Samba suite for Debian GNU/Linux.
#
#
# This is the main Samba configuration file. You should read the
# smb.conf(5) manual page in order to understand the options listed
# here. Samba has a huge number of configurable options most of which
# are not shown in this example
#
# Some options that are often worth tuning have been included as
# commented-out examples in this file.
# - When such options are commented with ";", the proposed setting
# differs from the default Samba behaviour
# - When commented with "#", the proposed setting is the default
# behaviour of Samba but the option is considered important
# enough to be mentioned here
#
# NOTE: Whenever you modify this file you should run the command
# "testparm" to check that you have not made any basic syntactic
# errors.
# A well-established practice is to name the original file
# "smb.conf.master" and create the "real" config file with
# testparm -s smb.conf.master >smb.conf
# This minimizes the size of the really used smb.conf file
# which, according to the Samba Team, impacts performance
# However, use this with caution if your smb.conf file contains nested
# "include" statements. See Debian bug #483187 for a case
# where using a master file is not a good idea.
#

#======================= Global Settings =======================

[global]

## Browsing/Identification ###

# Change this to the workgroup/NT-domain name your Samba server will part of
workgroup = SHOP

# This can be either the interface name or an IP address/netmask;
# interface names are normally preferred
; interfaces = 127.0.0.0/8 eth0

# Only bind to the named interfaces and/or networks; you must use the
# 'interfaces' option above to use this.
# It is recommended that you enable this feature if your Samba machine is
# not protected by a firewall or is a firewall itself. However, this
# option cannot handle dynamic or non-broadcast interfaces correctly.

#### Debugging/Accounting ####

# This tells Samba to use a separate log file for each machine
# that connects

# If you want Samba to only log through syslog then set the following
# parameter to 'yes'.
# syslog only = no

# We want Samba to log a minimum amount of information to syslog. Everything

####### Authentication #######

# "security = user" is always a good idea. This will require a Unix account

# This boolean parameter controls whether Samba attempts to sync the Unix
# password with the SMB password when the encrypted SMB password in the
# passdb is changed.
unix password sync = yes

# For Unix password sync to work on a Debian GNU/Linux system, the following
# parameters must be set (thanks to Ian Kahan <<kahan@informatik.tu-muenchen.de> for
# sending the correct chat script for the passwd program in Debian Sarge).
passwd program = /usr/bin/passwd %u
passwd chat = *Enter\snew\s*\spassword:* %n\n *Retype\snew\s*\spassword:* %n\n *password\supdated\ssuccessfully* .

If this is too obvious, please forgive me, but did you verify that the Samba service, smbd, is running?

I found several links that indicate that that can be a problem after a Ubuntu update. Here's one:

http://ubuntuforums.org/showthread.php?t=1318879

I tried this in terminal

rich@rich:~$ sudo /etc/init.d/samba restart
sudo: /etc/init.d/samba: command not found
rich@rich:~$

But it didn't work. Should I re-install Samba? I cannot get any folder to share in ubuntu 10.10 but get this error instead

'net usershare' returned error 255: net usershare add: cannot convert name "Everyone" to a SID. Memory allocation error.

Thanks

I also tried this in terminal

rich@rich:~$ sudo service smbd start
[sudo] password for rich:
smbd start/running, process 5250
rich@rich:~$

But that didn't work either. when I do a status:
I get this after doing the smbd status

rich@rich:~$ service smbd status
smbd stop/waiting
rich@rich:~$

It says it's running but when I try to share a folder/file i still get the prior error

'net usershare' returned error 255: net usershare add: cannot convert name "Everyone" to a SID. Memory allocation error.

Also tried this in terminal but still no go

rich@rich:~$ shares-admin

(shares-admin:5461): Gtk-CRITICAL **: IA__gtk_entry_set_text: assertion `text != NULL' failed
rich@rich:~$


Something isn't right. I, with your help, would like to solve.

Thanks

I think you are running into the same problems I have been running into.

I have been running SAMBA for a while, had a wonderful configuration smb.conf file that worked like a charm. . .

Then I upgraded. . .It upgraded SAMBA also. . .

Result is, SAMBA shut down immediately, lost all users, conf file is full of errors, etc.

I am (right now) trying to search for some config setups to the SAMBA that works.

Even the simple things did not work. . .

My link is the following:

http://www.linuxquestions.org/questi...etwork-907190/

My problem (as someone pointed out) was a upgrade to Samba.

valid users command quit working, which caused many errors.
MaxLog size stopped working.
and many others.

Thanks DrWayne:

I cannot get the ubuntu box to allow me to create a shared folder at all, all I did was keep up with 10.10 up grades. I try to restart samba in terminal, but it says command not found. used a whole bunch of commands found on threads but none worked yet. I will keep searching for a solution, maybe together we can find one. Maybe we have to re install samba, I don't know though, I am kind of afraid to do that just yet. Please keep me informed as to anything you might find and I will do the same.

I have usually found that starting Samba in a terminal does not work unless I cd to /etc/samba first. Then the command is smbd restart.

I check whether it's running with ps:

I had to restart it once after the upgrade. Since then it's restarted on boot.

During the upgrade, I told Ubuntu not to overwrite my smbd.conf file, so it was undisturbed. If you let Ubuntu overwrite it, you will have to recreate it.

Here's mine (somewhat expurgated); it's just a simple little configuration for a simple little home network:

Hello:

I tried the command "ps -A | grep smbd" and it didn't work at all, nothing happened in terminal no message, nothing. Not quite sure what you mean by "cd/etc/samba". There is no samba in my "etc" folder. Any folders with samba is in "etc/int" and "etc/int.d". I am running ubuntu 10.10, updates are up to date. I am afraid to upgrade to 11.04 as I see too many problems with wireless connections in the forums. I tried a lot of commands referring to samba, start, restart, stop etc, none work at all. The only one that works is status, it tells me "stop/waiting". I cannot get permissions to work either using share>properties menu. Something is not letting me set file/folder shares and permissions. Is there anywhere else I could troubleshoot?

Oh by the way, the ubuntu computer can access the windows shared folders with no problems at all I can transfer files that way between computers. It was much nicer when both computers where able access shared files/folders in both directions. It's as if file and print sharing is turned off in ubuntu and won't let the windows xp machine access any shared folders

Here is my samba status code result:

rich@rich:~$ smbstatus

Samba version 3.5.4
PID Username Group Machine
-------------------------------------------------------------------
<processes do not show up in anonymous mode>

Service pid machine Connected at
-------------------------------------------------------

No locked files

rich@rich:~$

Thanks:
rjs1943

I found the problem and it's working now. I right clicked on the shared folder went to permissions and changed the Group from sambashare to the username on the ubuntu computer. I don't know how it got changed. Anyway shares on the ubuntu machine can be accessed from the windows xp machine. Thanks to everyone who responded on this thread.

Thanks to All:
